HORIZONTAL BAR.

Specification of Letters Patent. Patented 31 21,

Application filed April 27', 1920. Serial No. 376,969.

T0(r71w/zm/titmcy concern:

Be it known that we, Finn) Wrrnnnrs and Lonnxrs II. S'rrxvio, citizensof the Iinited States. and residents of Bellingham, county of \Yhatcom,and State of \Vashington, have invented certain new and usefulImprovements in Horizontal Bars, of which the following is aspecification. f

This invention relates to supporting strncture for horizontal bars, andhas for its principal object toprovide collapsible frame members whichmay be extended to functional position to hold and rigidly support ahorizontal bar or the like, and which may be folded together, orcollapsed to release the bar and permit it to be packed or stored withthe frame members in a minimum amount of space.

It is also an object of the invention to provide supporting frames ofthis character of simple and durable construction which willsubstantially support a bar against lateral or longitudinal strain andyet have no fixed connection therewith; which allows quick and easydisassembling of the parts.

In accomplishing these and other objects of the invention, we haveprovided the improved details of structure, the preferred forms of whichare illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a set of bar supporting framesembodying the pres ent invention in functional position.

Figure 2 is an end view of the same. show ing in dotted lines, themanner of folding the legs together to release the bar, and showingextension members fixed to the legs.

Figure 3 is a view of a frame when in collapsed position.

Figure 4 is an enlarged detail View, illustrating a curved connectingbolt which secures the upper ends of the legs of a frame together.

Referring more in detail to the drawings: 1 designates a horizontal baror the like, which is supported at its opposite ends by means of framestructures 2 embodying the present invention. Each of these framescomprises two legs, 3, which are spaced apart at their lower ends and attheir upper ends have faces a cut on a bevel thereto, which are broughttogether in a vertical joint; thus forming an inverted V-shaped frame.

The 0 posed faces 4 of the providec with seats, or notches,

legs 3 are each 5, which as shown in Figures 1, 2 and 3, aresemi-circular and register with each other so that,,when

tne legsare brought together they will act co-operatively to grip andseat the-end of a bar 1 therein.

Radiall curved bolts 7 extend sli'dably through apertures 8, adaptedthereto atpoints a little below the upper ends of the legs. These boltsare provided with heads 9 at one end and have nuts 10 threaded ontotheir opposite ends which may be "adjusted to adapt the gripping orrod-supporting ends I to various sizes of rods. The slidable mounting ofthe bolts also permits folding of the legs together, as is shown inFigure 3.

At their lower ends, the legs are spaced apart and braced by a pair ofhingcdly connected bars 12 and 18, which, at their outer ends, are alsohingedly connected to the legs. This particular manner of bracing limitsthe spread of the legs, normally prevents them from being movedtogether, but permits folding of the paired bars together, on movingtheir hingcdly connected ends upwardly, so that the legs may be movedtogether and thereby release the bar from the notches at their upperends.

It is also .desired that the notches 5 extend across the faces 4: in amanner that when the bar 1 is seated it will cause the frames to beinclined toward each other at their upper ends and will thus brace thebar against longitudinal movement. It is also desired to provide thebase of each leg with a shoe or pad of rubber, or the like, 20, whichwill prevent slipping.

In Figure 2 we have illustrated the attachment of extension legs 15tothe legs 3. This is done by extending the lower ends of the legs 15through loops formed by bands 16, fixed to the lower ends of the legs 3and securing their upper ends to the legs 8 by bolts 17, which may beextended through registering apertures 18 in the legs.

In Figure 4 we have illustrated the mounting of a square bar in thesupporting frame. In this construction the notches 5 are cut squareinstead of semi-circular notches, and may be made to correspond to thecharacter of the bar used, and may be semi-circular, square,semi-hexagonal, many other neces sary or desired shape to fitcorrespondingly shaped ends of the bars supported.

In using frames of this character, it 18 only necessary to place the endof a bar within the notches 5, and to spread the legs apart, as inFigure 2, to draw ends of the legs tightl a ainst the opposite sidesofthe bar en he tension with which the legs grip the bar ends may be ad-,justed by ad ustment of the nuts at the ends of the bolts. 1

To release the bar, it is only necessary to pair of diverging legs cuton a bevel at their the upper upper ends and adapted to be fitted togather in a vertical joint, the beveled portions having notches cuttherein to cooperatively receive and support an end of the bar therein,a bolt curved radially about the bar and functionally connecting thelegs at points below the upper ends and having an adjustable nut at oneend thereof and extending slidably through apertures in the legs, andcollapsible brace members connecting the lower ends of the legs adaptedto be extended to spread the legs apart to force them together at theirupper ends to grip the bar .and to be folded together to permit theupper ends to release the bar.

Signed at Bellingham, Whatcom County, Washington, this 14th day ofApril, 1920.
